The ebuild needs to be updated to build the packages from source
Created attachment 44724 [details] datavision-0.8.2.ebuild the ebuild which builds datavision from source. it also removes packed jar issues
Created attachment 44725 [details] build.xml a new build.xml for datavision, the original one is horrible and the author himself wrote an comment into the packed one which says that it shouldnt be used
Created attachment 44726 [details] datavision.sh a startup script for datavision which creates a local classpath containing pathes to the needed jars at runtime. depending on which database is used (set by useflag) the matching jdbc driver will also be included to the classpath.
Fixed. Available for testing as dev-java/datavision-0.8.2
